- Add option to reprogram FPGA every reboot, enable this as default in
  chameleonv3 defconfig.
- Fixes: Rename CONFIG_SPL_SOCFPGA_SEC_REG to CONFIG_SPL_SOCFPGA_DT_REG,
  so the driver can be built when CONFIG_SPL_SOCFPGA_DT_REG is set in
  defconfig.

Arria 10 FPGA is only programmed during the cold boot.
This option forces the FPGA to be reprogrammed every reboot,
allowing to change the bitstream and apply it with warm reboot.
